Abstract

The invention provides atest system for an engine driver display unit. The system comprises a main processing unit simulator, a traction control unit simulator, an auxiliary control unit simulator, a brake control unit simulator and an engine driver console simulator, wherein the main processing unit simulator, the traction control unit simulator, the auxiliary control unit simulator, the brake control unit simulator and the engine driver console simulator are mutually connected through a factory instrument protocol vehicle network so as to simulate engine equipment and package the generated simulated data into a data packet which is then sent to a to-be-tested engine driver display unit connected to the factory instrument protocol vehicle network. The test system for the engine driver display unit, provided by the invention, is used for simulating the engine equipment to carry out data interaction with the engine driver display unit through the arrangement of the main processing unit simulator, the traction control unit simulator, the auxiliary control unit simulator, the brake control unit simulator and the engine driver console simulator, so that the ground test property of the engine driver display unit is realized.

Description

technical field [0001] The invention relates to a structure technology of a locomotive equipment test system, in particular to a locomotive driver display unit test system. Background technique [0002] The control systems of modern high-power AC drive electric locomotives are all based on the network structure, and the World FIP (World Factory Instrumentation Protocol, World FIP for short) network is one of the networks. The World FIP network is divided into a vehicle network and a train network. The vehicle network is mainly used for information exchange between the internal equipment of a single locomotive. The internal equipment of the locomotive usually includes: driver display unit, main control unit, traction control unit, auxiliary control unit, brake control unit and driver console. The main function of the driver display unit is to capture and collect periodic process data, non-periodic process data and non-periodic message data of other equipment inside the locom...
